Y House

The house, located on a hilltop in Tunquén, a coastal town an hour from Santiago, was designed as a beach residence that would become a permanent home in the future. The client sought an unconventional dwelling.
When evaluating the site, the highest point of the hill was identified as the ideal location due to its views, despite its exposure to strong winds, which became a key design challenge. Given the size of the property, a 360-degree integration was sought, allowing for panoramic views of the surroundings.

The house's layout was conceived in a "Y" shape. The public spaces, such as bedrooms, library, barbecue area, and gym, are organized into two arms that encompass almost 120 degrees of views, creating a sheltered central terrace. The living room is located at the junction of these arms, while a third arm, facing the access road and the hills, houses the service areas (garage, storage room, and battery rooms). Being at the highest point and coinciding with the access, this floor plan was established as the base, with the ocean-facing volumes conceived as two structures connected by split levels around a higher central space.

A central architectural element is a circular skylight located at the geometric center of the house. This skylight not only provides constant indirect light but also constructively resolves the roof junctions of the three Y-shaped structures. In terms of construction, the house was designed with the fewest possible structural axes, based on a 1.2-meter grid to optimize the use of wood. For the exterior, dark-toned, heat-treated wood was chosen, which helps reduce the high maintenance costs typically associated with coastal environments, while the interior contrasts with lighter-toned pine paneling.

Finally, a crucial aspect of the design was sustainability, as the area lacks basic services such as electricity, potable water, and sewage. Therefore, the house incorporates solar panels to generate its own energy and has a wastewater treatment plant. This autonomy in services was a fundamental consideration from the initial stages of the project, ensuring that the house not only integrates aesthetically with its surroundings, but also functions efficiently and self-sufficiently in a remote area.

Also a enviromental consultant was involved to review the ventilated facade system to make sure the house was cool enough during the warm months to avoid using AC equipement.
